Amatuer to (System) Administrator is finally ready for sale. A ton of work went into production, including three complete from-scratch restarts, about 50 hours of screencasting and editing, and so many Wiki lists that I've lost count. Please check out the Frequently Asked Questions for answers to the most common questions and concerns I have heard.
Linux is growing fast in both corporate and personal usage. If you cruise through postings at CareerBuilder, Monster, or any of the other "job" sites, you'll find plenty of postings looking for Linux experience. Some of them are Windows-centric with "Linux experience nice, but not neccesary." Others are six-figure Linux administration jobs requiring years of experience. Linux, and by extension Unix, skills are always in demand. My goal is to teach a new generation of administrators about Linux from installation to a useful server.
In my career, I've read a lot of help files, a lot of web sites, and a lot of archived emails. Those sorts of things are great for people who have an idea of what they're looking for already. But what if you want to run a Linux server, with zero knowledge, from scratch? In interacting with new Admins and users alike, I've come to the conclusion that video screencasts are the best method to build initial competence.
